H comnmnn Kmn AND saw.

To all whom it may cqncern:

Be itknownv that I, HAnoLn AIsUmR, a citizen of the United States, and aresident of Kearny, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in a Combined Knifeand Saw, in is a specification.

his intention has for its object to provide an attachment to an ordinaryknife, especially a'butcher lmife in the form of a saw blade at the rearedge thereof, and which will be of slightly greater thickness than theknife blade, to permit theblade to follow the saw in the kerf' or cutmade by the saw. v

Another object of the invention is to pro- I vide a device of thischaracter in which the vide a clamping ing a pair of arms 16 and 17,

a socket portion 18 square bore (see Fig. 4). 1 These arms are saw bladecan be readily attached and detached and also properly tensioned; and inwhich the attaching means also forms a guard to protect the fingers thatgrasp the handle.

In the accompanying drawing, one embodiment of my invention, 1 is a sideelevation of the device,

Fig. 2 is a top plan view,

Fig. 3 shows the point end of the knife and the attaching means for thesaw blade at that place,

Fig. 4 shows the attaching means other end of the knife,

5 shows the saw blade, and

showing Figure at the knife comprises of any desired to en age twoclamping pieces 11 and 12 (see ig. 3). These are secured at this place,as by rivets, and project beyond the part to receive one end of the sawblade 13. These projections are connected by 'a pin 14, and the blade 13may have a slot 15 curved toward the end of the saw blade, as shown,adapted to engage the pin 14,-as indicated in Fig. 1. At the other end Ipromember, shown as compristhat inclose at one end, having a secured onopposite sidesof the knife blade Specification of Letters Patent.Application filed ma ch 12, 19 21.

adjacent the handle, as shown in Fig. 1, and are of such length as toproject downwardly beyond the handle and blade, form a guard orprotector to prevent the hand or fingers of the user from slipping alongthe handle to the knife blade.

In the socket 18 slides a bar 19 that may be square or have flat sidesand has a forked portion 20 forming a slot crossed by a pin 21. This endof the saw blade is provided with a curvedslot 22 that .will engage thepin 21, when the blade is entered in this slot.

I nut 22 turns on the screw threaded end? portion 23 of the bar 19,which will serve to draw the bar toward the handle, and thereby tensionthe saw and retain it in position for use on the knife, as indicated inFig. 1. It will be seen that the curved or bent slots 15 and 22 in thesaw blade extend toward the ends of the blade to retain it in position,yet when the nut is loosened the blade is readily removed without takingout the plns.

I further provide a guard or cover for the edge of the knife, that canbe advanced to cover the knife edge, when the saw is to be used and canbe moved back to permit use of the knife. As shown I provide a series ofbent plates 24, 25, 26, 27, that can telescope together, as shown inFig. 1, adjacent the handle and which when drawn out as indicated inFig. 6 will serve to cover and protect the edge of the knife. Thesemembers can be attached to the clamping arms 16 and 17, if desired.

What Iclaim is:

A butchering implement including a blade and a handle, a clamp membersecured to the free end of the blade and adapted for engagement with asaw blade, a second clamp member comprising a square socket havingspaced depending integral arms secured to said blade adjacent thehandle, a square bar slidable in the socket and having a forked portionengageable with an end of HAROLD AIGUIEB.
